Correct answer: A — Increased digoxin concentration and bradycardia risk

This scenario assesses Digoxin verapamil in a UK pharmacy practice context. Verapamil can increase digoxin concentration and both can slow AV conduction. The best answer is Increased digoxin concentration and bradycardia risk because it addresses the principal clinical, legal or safety issue before routine supply. The other options are less appropriate because they either miss the key risk, delay necessary review, or would not meet expected BNF, NICE, MEP, MHRA or GPhC practice standards.
